Outcomes
Upon completion of this lesson, you should be able to:
- explain how the forward and reverse reaction rates in a chemical equilibrium are affected by changes in the temperature, pressure, concentration of a reactant or product, or the volume of the system.
- explain why the addition of a catalyst and varying the surface area of a reactant or product does not cause the equilibrium to shift, but does affect the time it takes to establish an equilibrium.
- state Le Châtelier's principle.
Prerequisites
Use a notepad, word processor or html editor to prepare responses to these items. Be prepared to share your answers with your teacher and/or your classmates.
- How does an increase in temperature affect a reaction rate?
- How does an increase in concentration affect a reaction rate?
- Compare endothermic and exothermic changes.
